screen. NOTE: If the water heater is located in an area that
is subjected to tint and dirt, it may be necessary to check
the base-ring filter more frequently.
2. Follow the Lighting Instructions to turn off the water heater
and allow it to coot for 10 minutes before attempting to clean
the base-ring filter.
3. Use a vacuum cleaner with a hose attachment to remove
any dust or debris that may have accumulated on the filter.
NOTE: If unable to inspect or clean the base-ring filter, follow
the "Cleaning the Combustion Chamber and Flame-arrestor"
instructions.

After the base-ring filter has been cleaned, follow the
Lighting Instructions to return the water heater to service.
Removing the Manifold/Burner Assembly

gas shut-off valve. This valve is typically located beside the
water heater (Figure 11). Note the position of the shut-off
valve in the open/on position then proceed to turn it off.
